Leyla is selling hot dogs and spicy sausages at the fair. She has only 40 buns, so she can sell no more than a total of 40 hot dogs and spicy sausages. Each hot dog sells for $2, and each sausage sells for $2.50. Leyla needs at least $90 in sales to meet her goal. Write a system of inequalities that models this situation.

lets say she sold x hot dogs and y sausage then x+y=40
2x+2.5y>90  
2x+2.5(40-x)>90
-0.5x+100>90
10>0.5x
20>x x<20
